The Music Reference RM10 was designed by Roger Modjeski for use with his Quad Electrostatics. New they are $1950 (good luck finding a used one - $1,000ish), they are small, only 14lbs, just six small inexpensive tubes with the power tubes (EL84) rated for 10,000 hours. Have no idea how they compare to the RW, but these are fantastic amps desinged by one of the great designers made for use with his Quads -- worth consideration, I think.
